Outdoor Research's ultralight Echo collection features an eco-friendly mesh fabric with AirVent moisture management to keep you cool and dry. Echo fabric has a soft hand feel, with inherent stretch and stink-free odour control for high-exertion activities.

ACTIVEFRESH™ ODOUR CONTROL
ActiveFresh™ provides active odour control that eliminates bad smells with long-lasting, durable freshness without jeopardising the fabric's breathability or softness. ActiveFresh™ is made from bio-based, silver-free technology that inhibits environmental odours, food-related body odours, and bacterial odours by actively preventing the buildup of bad smells during high-exertion sports.
